Come see this documentary thriller to learn how the NSA blocked its top code breaker, William Binney, from deployment of a universal surveillance system that could have prevented the 9/11 attacks, and later used that very system, stripped of safeguards, to spy on the American people. You’ll also hear from Mr. Binney, former CIA analyst Ray McGovern, and whistleblower Diane Roark. Moderator will be investigative journalist, Sean Stone.
